This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.

This study presented a case of tinea capitis in a 4-year-old without typical symptoms and traced the infection to Microsporum canis carried by domestic cats, highlighting the need for accurate diagnosis and appropriate treatment, especially in households with pets.

This study reported three related cases of woolly hair syndrome transmitted as a dominant autosomal trait, characterized by fine, frizzy hair and general hair thinning.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

This study used light sheet fluorescence microscopy to successfully image and analyze calcium oscillations in the root hairs of Arabidopsis thaliana, finding that these oscillations correlate with the root hair growth rate and that auxin affects these properties.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

This study demonstrated a method for delivering a photosensitizer, Ammi majus fructuum furocumarines, into hair follicles using calcium carbonate particles, followed by UVA irradiation, which led to significant pigment accumulation, indicating potential improvements for photochemical therapy.

This case report describes an eight-year-old Kashmiri boy diagnosed with monilethrix, a rare genetic hair disorder, characterized by a beaded appearance and fragility of the hair shaft.

This study used air wedge interferometry to measure the thickness of human scalp hair from three individuals, finding average thicknesses of 66.482 µm, 59.355 µm, and 59.927 µm respectively, within the typical range for adults.

This study introduces a new intracavity frequency modulation technique for tunable picosecond optical parametric oscillators, enhancing chemical contrast in coherent Raman imaging by allowing real-time subtraction of background signals.

This review discusses the nature, diagnosis, and control of mange in rabbits, focusing on its zoonotic implications and currently available treatment strategies, and reports no clinical results.

This review discusses the diagnosis and characteristics of dermatophyte infections and offers no new research findings, emphasizing the importance of microscopy and culture for accurate identification before treatment.

This article reports a case of a 19-month-old boy with scalp erythematous papules and hair loss, showing no improvement with initial treatment.

In this study, researchers analyzed spermogram data from men with diagnosed infertility in Ukraine, aiming to identify the most common sperm disorders, and they found that the study primarily involved men with primary infertility, compared to a control group of healthy men with confirmed fertility.

This study analyzed animal hairs from 18th-century burial sites in Mazamet, France, reporting distinct hair morphologies consistent with the use of common local animal furs such as goat, badger, cow, or horse, reflecting the modest socioeconomic status of the individuals interred.

This review discusses the applications of low level laser therapy (LLLT) in wound healing, pain reduction, and treating various conditions, but reports no new clinical results; the authors highlight the need for randomized controlled trials for serious diseases.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This review discusses the applications and advantages of LED-based photobiomodulation therapy for dermatological and cosmetic purposes but highlights existing challenges and health concerns while exploring future perspectives.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This study reports that Elvitegravir, a drug currently approved for other uses, shows potential as a neuro- and mitoprotective agent by attenuating mitochondrial damage caused by NMDA receptors in primary mouse cortical neurons.

Low-Level Laser Therapy can stimulate healing and cell function, potentially leading to wider medical use.

The document concludes that the trichogram is a useful tool for diagnosing hair loss and suggests semi-organ cultures for practical trichological research.

This article discusses hair and nail research contributions in dermatology but reports no new clinical findings.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

This review updates on various methods for hair and scalp examination, encompassing non-invasive, semi-invasive, and invasive techniques, and reports no new results.
